Abstract

L'invention concerne une lampe de secours à longue durée de vie et qui est produite à moindre coût. La lampe de secours comprend des condensateurs (DLC 8, 10) qui se chargent pendant que la lampe est alimentée en courant, des moyens de commutation (circuit de commutation 16) qui sont connectés électriquement lorsqu'une interruption de courant est détectée, et des diodes électroluminescentes (DEL à luminance élevée 2, 4, 6) qui s'allument grâce à la décharge des condensateurs mentionnés lorsque les moyens de commutation sont électriquement connectés. On utilise pour les condensateurs une diode électroluminescente à haute luminance, et une diode électroluminescente qui émet de la lumière en se chargeant pour indiquer que les condensateurs se chargent.
